RSV et crise cardiaque : la vaccination, une priorité pour les patients cardiovasculaires

Hong Kong – 8 mai 2024 –

Le RSV, virus respiratoire syncytial, peut s’avérer dangereux, surtout pour les personnes fragiles. Un cas récent a révélé un lien direct entre l’infection au RSV et les crises cardiaques. Les experts soulignent que la vaccination est primordiale pour les personnes à risque, notamment celles souffrant de pathologies cardiovasculaires.Le Dr. Huang Wenhao, éminent cardiologue, explique les risques et les recommandations.

RSV Infection Can Trigger Heart Attacks: Experts Urge Vaccination for Cardiovascular Patients

Respiratory Syncytial Virus (RSV) often presents as a common cold, but for vulnerable individuals like the elderly and those with pre-existing conditions, it can be life-threatening. A recent case highlights the danger: a heart patient suffered a severe heart attack after contracting RSV and required emergency “Tongbozai” (angioplasty) surgery. Experts are now emphasizing the importance of RSV vaccination, particularly for high-risk individuals.

Cardiologist Dr. Huang Wenhao explains that while RSV typically causes mild upper respiratory symptoms like a runny nose, cough, or sore throat, it can lead to more serious lower respiratory infections, including pneumonia.This is especially true for those aged 75 and older, or individuals over 50 with chronic conditions such as COPD, asthma, diabetes, or heart disease. These individuals often experience more severe symptoms, diagnosed through lung examinations and blood oxygen level checks.

RSV and Cardiovascular Risk: A Perilous Connection

The link between RSV and cardiovascular health is becoming increasingly clear. Dr. Huang notes that RSV infection can increase inflammation in blood vessels,promoting coagulation and potentially leading to blockages. This significantly elevates the risk of heart attack and stroke.Studies show that patients with pre-existing conditions who contract RSV face a much higher risk of hospitalization. For example, those with chronic heart failure are eight times more likely to be hospitalized, while those with coronary artery disease face a 6.5-fold increased risk.

Dr. Huang shared a case of a previously healthy 70-year-old man who, despite never having been vaccinated against RSV, contracted the virus and developed severe pneumonia.He required ventilator support and later suffered an acute heart attack,necessitating emergency angioplasty. He spent two weeks in the hospital before recovering.

Limited Treatment Options: Prevention is Key

Currently, there are no specific antiviral drugs to treat RSV infections.Treatment focuses on supportive care, such as ventilators for pneumonia patients and cardiac medications for those with low blood pressure. Antibiotics may be necesary to combat secondary bacterial infections like pneumonia, sinusitis, or otitis media.

Vaccination: Your Best Defense Against RSV

For individuals aged 60 and above, two RSV prevention vaccines are available in Hong Kong. One vaccine offers protection for nearly two years, with a 70-80% effectiveness rate in preventing severe illness during the first year. The other is an adjuvant RSV vaccine. Recent research published in a leading medical journal indicates that this adjuvant vaccine provides protection for at least three years, with a 90% effectiveness rate in preventing severe illness in the first year. The use of adjuvants enhances the vaccine’s effectiveness. This type of vaccine has been used for decades and is considered safe and effective. common side effects are mild and short-lived, primarily involving discomfort and fatigue at the injection site.
